摘　　要：对液压系统油液进行固体颗粒污染度检测是确保液压系统工作可靠性的有效手段,而金属微孔滤膜传感器在油液污染度检测过程中不受油液颜色及油液中水分和气泡的影响,其检测特点存在显著优势。综述金属微孔滤膜传感器的研制现状、微孔滤膜污染机制以及污染度检测模型的国内外研究现状,并提出在600目平纹不锈钢丝网表面化学镀镍来制备金属微孔滤膜传感器的一种新方法,以及利用Ruth的阻力理论来建立其污染度检测模型的新思路。Solid particle contamination level testing for oil samples is the most effective means to ensure the work reliabilities of hydraulic systems,and the metal micro-pore filter membrane sensor has significant advantages in the testing method since it is not affected by the color of oil and the water and air bubble in oil during the particle contamination level testing process. The current situation on the development of metal micro-pore filter membrane sensors,and the research status of the fouling mechanism and the contamination level testing model were reviewed. A new method to make the metal micro-pore filter membrane sensors by using electro-less nickel-plating on plain weave stainless steel wire meshes with size of 600 was put forward,and a new idea for the establishment of contamination level testing model according to Ruth＇s resistance theory was suggested.
